Spellman Introduces New EBM-FEG Integrated Multiple Output High Voltage Power Supply for Scanning Electron Microscope

New EBM-FEG Power Supply Unprecedented Image Quality and Resolution for SEM Requirements

January 22, 2019

Spellman High Voltage Electronics Corp, the world’s leading high voltage power supply, X-Ray generator and Monoblock® X-Ray source manufacturer, announces the introduction of their new integrated multiple output high voltage power supply specifically designed to drive scanning electron microscope columns. Spellman’s extensive knowledge in this application has enabled us to develop a range of technology platforms that can be customized to meet the demanding requirements of SEM.EBM-FEG Series  

The main acceleration voltage is a high stability 30kV supply, with integrated floating filament, extractor and suppressor outputs required to drive field emission, cold cathode and Schottky electron sources in a compact solution with extenders to mount in a 19” rack. All outputs are offered with ultra-low output ripple, excellent regulation, stability, temperature coefficient, drift and accuracy specifications. Isolation and control of the respective floating sources is provided via Spellman’s proprietary high voltage isolation techniques. 

Customer control of this integrated EBM-FEG power supply system is accomplished via a fiber optic interface. All high voltage safety interlocks are of a failsafe hardware based design and the EBM-FEG is CE marked and is designed to be compliant with applicable IEC, UL and SEMI standards. Spellman’s EBM-FEG offers exceptional performance with low ripple, micro-discharge, and ppm level stability for unprecedented image quality and resolution. Typical applications include Scanning Electron Microscopes and Electron Beam Controllers.
